What color wire is typically used for a ground branch circuit?

• A. Red
• B. Green
• C. White
• D. Black

Answer: (C)

The color wire that is typically used for a ground branch circuit is green. Ground wires are essential for safety, as they provide a path for electrical current to return to the ground in case of a fault, which helps prevent electrical shock or fire hazards. Green is universally recognized in electrical wiring standards as the color designated for ground conductors. This color coding is important for ensuring that anyone working with or inspecting electrical systems can quickly identify ground wires for safe handling and maintenance.

White is actually used for neutral wires in most electrical systems, not for grounding. Red and black wires typically serve as hot wires, carrying current to the load. Therefore, green is the proper identification color for ground conductors, in compliance with electrical codes and safety standards.
